The balance of Sam’s account, y, based on the number of weeks spent saving, X, can be represented by Y = 35X+10. The balance of his sisters account based on the weeks spent saving is shown on the paragraph. How much more money is Sam saving per week compared to his sister?
After five weeks, how much more will Sam have in his account than his sister? Pop

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
